NHTSA Complaint #11686600 — 2014 CHEVROLET MALIBU

Received vehicle at roughly 181,000 miles. Operated fine for about 5,000 miles and then began to show problems. In most cases when pressing down hard on the accelerator pedal, transmission drops into a lower gear and revs up to 5k rpm, cancelling cruise control, and staying there until accelerator is relieved. This makes accelerating more difficult since too much pressure on the accelerator pedal causes the car to get stuck at 5k rpm and stay at the same speed it is already at. This makes passing cars more dangerous as the car gets stuck at 5k rpm and can't pass the other vehicle, increasing the risk of a head on collision. Service engine and ABS lights are on as well as a service Stabilitrak notification in the driver information center. In addition, the outside temperature thermometer is faulty and shows much lower temperatures, such as -14 degrees during an 80 degree day. Vehicle is up to maintenance as far as my knowledge goes. Car has been previously junked twice and has a rebuilt title. There are no fluid leaks, the engine works well when the problem is not encountered, but it gets stuck at 5k rpm under hard acceleration more than it doesn't.
